In the early 1980s, the ratio of males to females in the top 0.01% of maths scores in SAT, the Scholastic Aptitude Test, was around 13 to 1. By the early 1990s it had fallen to four to one. After this, however, it remained obstinately unaltered (see chart). The other two tests, both of which post-date the period in which the SAT shows those huge changes, indicate less lopsided sex ratios of between two and three to one. But neither shows girls making much recent progress towards equality.
